Bioenergy Systems: Efficiency, Scale and Cost

Bioenergy systems differ in terms of efficiency, scale and cost. Due to the many different conversion options for biomass and its use across all energy carriers (gas, liquid, solid, heat, electricity) it is difficult to generalize. This can be seen as a complication when initiating national plans. Another complication in evaluating bioenergy conversion is the presence of several energy and non-energy products as part of the same set of production processes and/or within the same factory complex. Some basic bioenergy conversion issues are reviewed in this section.
